Each mobile terminal generally has a display screen, and the good outdoor visibility of the display screen has always been the direction pursued by display technology.

Limited by the technical capabilities and power consumption limitations of the terminal, the current mobile terminal display effect is not very good under outdoor strong light, because the ambient light reflected from the screen itself is too strong, doped in the image of the display screen, diluted Color rendering color reduces display contrast. For mobile phones and other mobile terminals, they are often used under outdoor glare. At this time, due to the specular reflection of the screen itself, the current relatively good design still has a reflection of about 5%. If the outdoor light is 100,000 lux, the ambient light is strong. Under illumination, the brightness of the screen will reach several hundred nits. The brightness of the display is a few hundred nits. At this time, the image light and the reflected light are mixed together, which seriously reduces the color expression and contrast of the displayed image, resulting in a decrease in display effect, making it difficult for the user to see the screen.

Therefore, the prior art has yet to be improved and developed.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention provides a color display method and system for a mobile terminal. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Please refer to FIG. 1. FIG. 1 is a flowchart of a preferred embodiment of a color display method for a mobile terminal according to the present invention. As shown in the figure, the method includes the following steps:

Step S100: detecting an ambient light intensity of an environment in which the mobile terminal is located;

Step S200, calculating a color enhancement scale factor according to the ambient light intensity;

Step S300, corresponding to enhancing the color display of the mobile terminal according to the color enhancement scale factor.

The above steps are described in detail below in conjunction with specific embodiments.

In step S100, the ambient light intensity of the environment in which the mobile terminal is located is detected. Specifically, a light intensity sensor can be disposed on the mobile terminal to detect the ambient light intensity of the environment in which the mobile terminal is located, and the unit of the light intensity is lux (lux), and the ambient light intensity of the environment in which the mobile terminal is located is obtained. Implementation, not to describe too much here.

In step S200, a color enhancement scale factor is calculated according to the ambient light intensity. Specifically, color enhancement is currently a widely used technology for displays that can make display colors more vivid but cause distortion. The enhanced scale factor can usually be adjusted based on the needs of the terminal designer. A fixed value of the compromise is usually chosen to ensure that the color distortion displayed in the outdoor room is within an acceptable range. The present invention combines this factor with ambient light intensity. Since the outdoor ambient light is mainly daylight, white or nearly white, the ambient light will dilute the displayed color, causing the color saturation to drop. The stronger the ambient light, the more the saturation drops.

According to this principle, in practical applications, the present invention provides the following formula to dynamically manage the color enhancement scale factor, thereby alleviating the drop in saturation. The step S200 specifically includes:

S210. Comparing the ambient light intensity L with a preset first ambient light intensity value L0. When L<L0, the color enhancement scale factor a is a preset first color enhancement scale factor of a0; when L≥ At L0, the color enhancement scale factor a= Min[a0+(L-L0)/Lmax, 1], where Lmax is the ambient light intensity value when the color enhancement is maximum.

Specifically, when L≥L0, a=Min (a0+(L-L0)/Lmax, 1); When L<L0, a=a0; where a is the color enhanced normalized scale factor; a0 is the initial value, when the indoor ambient light intensity L=L0, a=a0; Lmax is the defined color enhancement maximum The ambient light intensity, the ambient light exceeds the light intensity, may be some unexpected light intensity environment, the color enhancement does not change, and remains at the maximum. When L>L0, the color enhancement scale factor a takes the smaller value between a0+(L-L0)/Lmax and 1, which is the meaning of the Min() function.

In step S300, the color display of the mobile terminal is enhanced according to the color enhancement scale factor. In particular, current color enhancement is a widely used technique for display screens. The enhanced scale factor usually selects a fixed value of the compromise to ensure that the color distortion displayed in the outdoor room is within an acceptable range. Therefore, the present invention combines the color enhancement scale factor with the ambient light intensity, and the obtained color enhancement scale factor corresponds to the color display of the enhanced mobile terminal according to the existing color enhancement technique. How to perform color enhancement, the present invention is briefly described as follows.

The specific color enhancement process takes HSV space as an example. Switching to other color spaces is similar. First convert from RGB to HSV space: The H parameter represents the color information, ie the position of the spectral color in which it is located. This parameter is expressed in an angular amount, with red, green, and blue being separated by 120 degrees. The complementary colors are 180 degrees apart. Saturation S is a proportional value ranging from 0 to 1, which is expressed as the ratio between the purity of the selected color and the purity of the color. When S=0, there is only gray scale. V indicates the brightness of the color, ranging from 0 to 1. One thing to note: there is no direct connection between it and the light intensity.

The specific conversion is as follows: RGB conversion to HSV algorithm:

Max=max(R,G,B)

Min=min(R,G,B)

If R = max, H = (G-B)/(max-min)

If G = max, H = 2 + (B-R)/(max-min)

If B = max, H = 4 + (R-G)/(max-min)

H = H * 60

If H < 0, H = H + 360

V=max(R, G, B)

S=(max-min)/max

Color enhancement process:

The S component after the RBG is transferred to the HSV space is processed as follows:

S' = Min (S * (1+a), 1), where a is a color enhanced normalized scale factor;

The new S component after the saturation is increased, S'; S' has a maximum value of 1, and is still normalized.

Then process the HS’V and convert it to RGB:

If S’ = 0

R=G=B=V

Else

H /= 60;

i = INTEGER(H)

f = H - i

a = V * ( 1 – S’ )

b = V * ( 1 – S’ * f )

c = V * ( 1 – S’ * (1 - f ) )

Switch(i)

Case 0: R = V; G = c; B = a;

Case 1: R = b; G = v; B = a;

Case 2: R = a; G = v; B = c;

Case 3: R = a; G = b; B = v;

Case 4: R = c; G = a; B = v;

Case 5: R = v; G = a; B = b;

The color enhancement is processed.

In order to improve the display effect of the display screen, the step S200 further includes:

S220. Detect whether the display screen of the mobile terminal works in the maximum color gamut. If not, calculate the color gamut of the mobile terminal display to be operated according to the ambient light intensity and the color gamut mode of the current working display of the mobile terminal.

Specifically, regarding the color gamut mode, the display screen can operate in a standard mode or an SRGB mode, etc., which are gamut modes commonly used in the prior art. For some displays, if they employ high color gamut screens and color gamut management techniques, the present invention can be based on the introduction of ambient light variation factors to manage them. When the display works in the maximum color gamut, such as the color gamut value is S0, Ambient light does not cause any change in the color gamut, and still maintains the highest color gamut S0; when for some reason (real display or brand feature display), when the display works in gamut mode S1, the gamut value S1 is less than S0. The color gamut is dynamically adjusted according to the ambient light, and the increase of the color gamut means that the color saturation is improved, and the problem of saturation reduction due to ambient light can also be alleviated.

In actual application, the step S220 specifically includes:

S221. When the display screen of the mobile terminal does not work in the maximum color gamut, calculate a color gamut factor b corresponding to the display screen of the mobile terminal according to the ambient light intensity L; when L<L0, the color gamut factor b=0; When ≥ L0, the color gamut factor b = Min [(L-L0) / Lmax, 1]; wherein L0 is a preset first ambient light intensity value, and Lmax is an ambient light intensity value when the color enhancement is maximum;

S222. Calculate a color gamut S=S1+b*(S0-S1) of the mobile terminal display to be operated, where S0 is the color gamut value when the display screen works in the maximum color gamut; S1 is the color gamut value corresponding to the color gamut mode in which the display is currently working.

Specifically, when L ≥ L0, the gamut factor b is a small value between (L - L0) / Lmax and 1, which is the meaning of the Min () function. The color gamut of the mobile terminal display is calculated according to the color gamut mode and the ambient light intensity of the current working display of the mobile terminal, and then the working color gamut of the display screen is adjusted accordingly, thereby dynamically adjusting the color gamut of the display screen, thereby alleviating The problem of saturation reduction caused by ambient light improves the outdoor display effect.

Further, the step S300 further includes: S310, according to the calculated color gamut of the mobile terminal display to be operated, corresponding to adjusting the color gamut of the mobile terminal display operation. Specifically, gamut adjustment is a way of digital transformation. According to the color space conversion theory, if the display of the S color gamut is to be displayed on the display screen of the maximum S0 color gamut, the digital image of the color gamut space needs to be first transformed into a device-independent color space, such as CIE. XYZ space, on the basis of this space, according to the color coordinates of the specific three primary colors of the S0 color gamut, a conversion matrix such as H can be obtained. On this basis, for the specific image of the gamut space S, first pre-process, then convert to CIE The XYZ space is then operated with the conversion matrix H of the high color gamut space S0, and then post-processed to achieve the effect of the color gamut mode S. The specific process is as follows, first obtain the target color gamut S[R, G, B], and then preprocess the matrix operation to CIE The XYZ space [X, Y, Z] is converted into the original color gamut S0[R', G', B'] according to the conversion matrix H, and the post processing is the display color gamut S[R, G, B]. The display of the excellent domain space S is displayed on the display hardware of the maximum color gamut space of S0.

The color display method of the mobile terminal provided by the invention is an adaptive image processing method, which can dynamically adjust the color enhancement according to the intensity of the ambient light without significantly increasing the power consumption and ensuring the display effect, further The color gamut range can also be adjusted, and the outdoor display effect can be improved without affecting the display effect under the indoor low light.
